'rns'rnnnn Specification of Letters Patent.

Patented Apr. as, 1919.

Application filed August as, 1917. Serial No. 187,804..

To all wltom it may concern Be it known that I, Mosns, F. CARR, a

citizen of the United States, and a resident vented an Improvement inFasteners, of'.

which the following description, in connection with the accompanyingdrawings, is a specification, like characters on the drawingsrepresenting like parts.

This invention pertains to improvements in fasteners, and moreparticularly, though not exclusively, to snap fasteners primarilyintended to hold on securely the flaps of pockets containing clips ofcartridges, readily permitting separation of the two parts of thefastener so that the flap can be raised and the clip of cartridgesremoved from the pocket, while reducingto a minimum the chances ofaccidental separation of the fastener and resultant loss of ammunition.

In snap fasteners as ordinarily constructed, if the flap of the pocketwere raised accidentally in climbing out of a trench or by catching onthe bough of a tree or the like, the socket portion of the fastenerwould be separated from the stud portion thereof. The use of those typesof separable fasteners requiring any considerable manipulation forseparation of the parts is disadvantageous because valuable time may belost on account of failure to immediately perform the correctmanipulation. In the present invention the amount of manipulationnecessary to open the devicje is reduced to a minimum.

In the drawings:

Figure 1 is an elevation of a" preferred form of one embodiment of myinvention;

Fig. 2 is a section on the line 22 of Fig. 1;

Fig. 3 is a section on the line 33 of Fig. 2.

Referring to the drawings, 4 represents the side of a coat, 5 theoutside of a pocket and 6 the flap of the pocket. The stud 7 is attachedto the outside of the pocket 5 by any suitable means and provides around head 8 and a neck portion 9 providing shoulders, preferablyabrupt, between the neck 9 and the head, 8. The socket is attached tothe flap 6 of the pocket and preferably comprisesa front plate 10,intermediate plate 11 and back plate 12. The front plate 10 ispreferably flanged at the edges to provide a recess for a spring 13which provides jaws I 14 and 15 extending transversely of the socket.The jaws 14: and 15 are preferably held apart by a projection 16interposed between their ends. When the rounded head of the stud 8 ispressed between the jaws 14k and 15, the jaws are spread and engage theneck 9 of the stud. As before stated, the shoulders provided between theneck 9 and head 8 are preferably sufficiently abrupt to preventseparation of the stud and socket by rectilinear movement. Saidshoulders are also preferably sufliciently abrupt to prevent separationof the jaws 14 and 15 by tipping movement of the socket relative to thestud in a direction transverse to the jaws. Relative tipping movement ofthe stud and socket in a directionlongitudinal of the jaws 14.- and 15is preferably prevented by the intermediate plate 11 or the back plate12 or both of said plates.

The aperture through the intermediate and back plates is preferably suchas to permit tipping movement of the socket relative to the stud whenthe bottom'of the flap 6 is pulled outwardly. As before stated, however,this alone will not open the fastener because of the engagement betweenthe abrupt shoulder of the stud and the jaw 15. When, however, the flap6 is pulled down- 'wardly and outwardly in the direction shown by thearrow in Fig. 2, the jaw 14 is pressed upwardly by the stud 7 while thejaw 15 re mains abutted against the stop 16 of the socket casing.Therefore the jaws '14: and 15 are separated sufficiently to permit thehead 8 of the stud 7 to slip between the jaws 14 and 15, thereby openingthe fastener andpermitting removal of the contents of the pocket. Inpractice the stud and socket are so proportioned that a quick jerk in adownward and outward direction will effect this opening. It is obviousthat movement in this direction can only be effected in oneway, v-iz.,'by graspin the bottom of the flap of the pocket in a su ciently firmmanner so as to be able to exert tension thereon in the desireddirection. 7

While I have shown and described one embodiment of my invention, it isobvious that changes involving omission, alteration, substitution andreversal of parts, and even changes in the mode of operation, may bemade without departing from the scope of my invention, which is bestdefined in the following claims.

Claims:

1. A fastener comprising, in combination,

a stud, a socket, jaw means carried by said socket for engagement withsaid stud, and means cooperating with said jaw means providing foropening thereof on diagonal movement of said socket in a directiontransverse to, away from, and in the direction of the longitudinal axisof said stud.

2. A separable fastener comprising, in combination, a stud, a socket, aplurality of resilient jaws carried by said socket, stop tivelyinterposed between the ends of said jaws; said socket permitting bodilytransverse movement of said socket relative to said stud to a positionwhere one of said jaws is disengaged from the abrupt portion of saidshoulder.

4. A stud and socket fastener comprising, in combination, a stud havinga head and a neck with an abrupt shoulder interposed therebetween, asocket providing two sub-- stantially parallel jaws for engagement withopposite sides of said neck and means permitting disengagement of one ofsaid jaws from the abrupt portion of said shoulder, thereby to permitseparation, of said socket from said stud on continued tipping movementof said socket relative to said stud in a direction transverse to saidjaws.

-, 5. A stud and socket fastener comprising,

in combination, a stud having a head and a neck, an abrupt shoulderinterposed between said head andneck, a socket having a casing, aresilient spring inclosed in said casing and providing two resilientjaws, a stop interposed between the ends of-said'jaws and meanspermitting limitedtippin movement of said socket relative to said studin a direction transverse to said jaws, thereby to permit separation ofsaid stud from said socket.

6. A stud and socket astener comprising, in combination, a stu 7 havinga head 8 and a neck 9, an. abrupt shoulder interposed between said headand said neck, a socket comprising a casing 10 having a spring 13therein providing. resilient aws 14 and 15, and a stop 16 interposedbetween the ends of said jaws. j

7 A stud and socket fastener comprising, in combination, a stud havin ahead and a neck; a socket therefor having jaw means and means opposingseparation of said socket from said stud by rectilinear movement ofsaidsocket relative to said stud or by tipping movement alone, whilepermitting separation of said socket from said stud by combinedtransverse and outward .movement of one side of said socket relative tosaid stud.

8. A fastener for the flaps of cartridge pockets providin a stud 7attached to the outer portion 0 the pocket, a socket attached to theflap 6 of the pocket, jaw means carried b said socket for enga ementwith a reduce portion-of said stud g and means opposing separation ofsaid stud from said socket by rectilinear movement of said socketrelative to said stud or by relative tipping movement alone, whilepermitting separation of said socket from said stud by a combineddownward and outward pull on the bottom of said flap.
